N-azinyl-N&#39;-(het)arylsulphonyl-ureas

ABSTRACT

The invention relates to novel N-azinyl-N&#39;-(het)arylsulphonyl-ureas of the formula (I), ##STR1## in which J represents J-1 to J-4, where J-1 to J-4 have the following meanings: ##STR2## in which E represents a direct linkage, alkyl ene, oxygen, alkylamino or sulphur, 
     and in which 
     A represents N or CR 11  (where the radicals R 1  -R 11  have the meanings given in the description), 
     to several processes and novel intermediates for their preparation, and to their use as herbicides.

The invention relates to novel N-azinyl-N'-(het)arylsulphonyl-ureas, to processes and novel intermediates for their preparation, and to their use as herbicides.

It is already known that certain N-azinyl-N'-arylsulphonylureas having simple open-chain hydroxamic ester groups in the aryl moiety, such as, for example, N-(4,6-dimethylpyrimidin-2-yl)-N'-(2-methoxyaminocarbonyl-phenylsulphonyl)-urea and the corresponding-N'-(2-n-octyloxyaminocarbonylphenylsulphonyl)-urea, exhibit herbicidal properties (cf. DE-A-3 516 435; EP-A-173 958; U.S. Pat. No. 4,704,158). However, the herbicidal effect of these known compounds is not satisfactory in all respects.

In addition, certain herbicidally-active N-azinyl-N'-(het)arylsulphonyl-ureas have also become well known which are substituted in the (het)aryl moiety by O,O-dialkylated, likewise open-chain hydroxamic acid groups (cf. EP-A-301 784); by contrast, corresponding cyclic hydroxamic acid derivatives have not hitherto been described.

Novel N-azinyl-N'-(het)arylsulphonyl-ureas of the general formula (I) ##STR3## have now been found in which A represents nitrogen or a CR¹¹ group,

where

R¹¹ represents hydrogen, alkyl, halogen and haloalkyl,

R¹ represents hydrogen or an optionally substituted radical from the series alkyl, alkoxy, alkoxyalkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aralkyl and aryl,

R² represents hydrogen or halogen, or represents alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having in each case 1 to 6 carbon atoms which are in each case optionally substituted by halogen,

R³ represents hydrogen or halogen, or represents alkyl, alkoxy, alkylthio, alkylamino or dialkylamino having in each case 1 to 6 carbon atoms which are in each case optionally substituted by halogen,

J represents J-1 to J-4, where J-1 to J-4 have the following meanings: ##STR4## in which E represents a direct linkage, alkylene, oxygen, alkylamino or sulphur,

R⁴ -R⁷, independently of each other, represent hydrogen, halogen, cyano or thiocyanato, or represent alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl or alkylaminocarbonyl having in each case 1 to 3 carbon atoms which are in each case optionally substituted by halogen,

R⁸ represents hydrogen or an optionally substituted radical from the series alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aralkyl and aryl, or represents a group C(=O)R⁹,

where

R⁹ represents hydrogen, optionally substituted alkyl, optionally substituted aryl, alkoxy, alkylamino or dialkylamino,

R¹⁰ represents hydrogen, halogen, cyano or thiocyanato, or represents alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl or alkylaminocarbonyl having in each case 1 to 3 carbon atoms which are in each case optionally substituted by halogen,

where, in the abovementioned radicals, the alkyl and alkylene groups can in each case contain 1 to 6 C atoms, the alkenyl and alkinyl groups in each case 2 to 6 C atoms, the cycloalkyl groups in each case 3 to 6 C atoms and the aryl groups in each case 6 or 10 C atoms,

as well as salts of compounds of the formula (I).

Accordingly, the (5,6-dihydro-[1,4,2]-dioxazin-3-yl) radical, as a novel, heterocyclic substituent in the (het)aryl moiety of the N-azinyl-N'-(het)arylsulphonyl-ureas, is a characteristic structural feature of the novel sulphonylureas (I). The simple parent substance, which is not further substituted, of this compound class - (5,6-dihydro-[1,4,2]-dioxazin-3-yl)benzene, which can also be termed 3-phenyl-5H-1,4,2-dioxazine --is known (cf. J. E. Johnson et al., J. Org. Chem., Vol. 36 (2), (1971), pp. 284-294).

The novel N-azinyl-N'-(het)arylsulphonyl-ureas of the general formula (I) are obtained when

(a) (het)arylsulphonamides of the general formula (II),

    J--SO.sub.2 --NH.sub.2                                     (II)

in which

in which

These radical definitions can be combined arbitrarily among themselves, that is also between the given preferred ranges.

The substituted alkanes which are additionally to be used as starting compounds in process (e) are defined generally by the formula (IX). In formula (IX), the substituents R⁴, R⁵, R⁶ and R⁷ preferably or in particular have those meanings which have already been indicated above, in connection with the description of the compounds of the formula (I), as being preferred or particularly preferred for R⁴ -R⁷ ; the reactive, vicinal leaving groups X and Y have the preferred meanings which have already been indicated for formula (IX).

The following may be mentioned as examples of particularly suitable compounds of the formula (IX):

1,2-dichloroethane, 1,2-dibromoethane, 1,2-diiodoethane, 1,2-bis(methanesulphonyloxy)ethane, 1,2-bis-(trifluoromethanesulphonyloxy)ethane, 1,2-bis(trifluoroacetyloxy)ethane and 1,2-bis-(4-toluenesulphonyloxy)ethane.

The starting compounds of the formula (IX) are known without exception and some of them are commercially available as chemicals for use in syntheses.

Finally, it has been found that the novel (het)arylthiobenzyl ethers of the above formula (VII), which are required for process (d), are obtained when

(f) (Het)arylthiobenzylcarboxylic esters of the formula (X) ##STR17## in which T has the meanings indicated above for process (e),

are reacted with hydroxylamine hydrochloride and a substituted alkane of the formula (IX), ##STR18## in which R⁴ -R⁷ have the above-indicated meanings, and

X and Y, independently of each other, represent halogen, or represent alkylcarbonyloxy, arylcarbonyloxy, alkylsulphonyloxy or arylsulphonyloxy, which are optionally substituted (preferably represent chlorine, bromine, iodine, C₁ -C₆ -alkylcarbonyloxy, C₆ -C₁₂ -arylcarbonyloxy, C₁ -C₆ -alkylsulphonyloxy or C₆ -C₁₂ -arylsulphonyloxy),

optionally in the presence of an organic diluent and optionally in the presence of a reaction auxiliary.

If, for example, methyl 2-benzylmercaptobenzoate, hydroxylamine hydrochloride and 1,2-dibromoethane are used as starting compounds for process (f), the course of the reaction can then be outlined by the following reaction scheme: ##STR19##

The (het)arylthiobenzylcarboxylic esters which are required as starting compounds for preparing compounds of the formula (VII) in process (f) according to the invention are defined generally by formula (X); that which has been said above in relation to process (e) applies for the meaning of the group T.

The following may be mentioned as examples of the intermediates of the formula (X):

methyl 2-benzylmercaptobenzoate, methyl 2-benzylmercapto-6-methyl-benzoate, methyl (2-benzylmercaptophenyl)-acetate, methyl 2-benzylmercaptopyridine-3-carboxylate, methyl 1-methyl-5-benzylmercaptopyrazole-4-carboxylate, methyl 1-methyl-3-chloro-5-benzylmercaptopyrazole-4-carboxylate and methyl 3 -benzylmercaptothiophene-2-carboxylate.

The starting compounds of the formula (X) are known and/or can be prepared by processes which are known per se (cf., e.g., Chem. Pharm. Bull., 34(2), 540-9 (1986), J. Hetero-cycl. Chem. 15(3), 513-14 (1978)).

The substituted alkanes of the formula (IX) which are additionally to be used as starting compounds in process (f) have already been described above in more detail for process (e).

The processes (a), (b) and (c) according to the invention for preparing the novel compounds (I), the processes (d) and (e) according to the invention for preparing the novel intermediates of the formula (II), and the process (f) according to the invention for preparing the novel intermediates of the formula (VII), are preferably carried out using diluents. In this context, practically all inert organic solvents are suitable for use as diluents. These preferably include--except for process (d)--aliphatic and aromatic, optionally halogenated hydrocarbons, such as pentane, hexane, heptane, cyclohexane, petroleum ether, benzine, ligroin, benzene, toluene, xylene, methylene chloride, chlorobenzene and o-dichlorobenzene, ethers, such as diethyl ether and dibutyl ether, glycol dimethyl ether and diglycol dimethyl ether, tetrahydrofuran and dioxane, ketones, such as acetone, methyl ethyl ketone, methyl isopropyl ketone and methyl isobutyl ketone, esters, such as methyl acetate and ethyl acetate, nitriles, such as, for example, acetonitrile and propionitrile, amides, such as, for example, dimethylformamide, dimethylacetamide and N-methylpyrrolidone, as well as dimethyl sulphoxide, tetramethylene sulphone and hexamethylphosphoric triamide.

In the main, it is only the previously mentioned chlorinated solvents which are suitable for use as diluents in the chlorination process (d).

The processes (a), (e) and (f) according to the invention are optionally carried out in the presence of a reaction auxiliary. These preferably include basic organic nitrogen compounds, such as, for example, trimethylamine, triethylamine, N,N-dimethylaniline, N,N-dimethylbenzylamine, pyridine, 4-dimethylaminopyridine, diazabicyclooctane (DABCO), diazabicyclononene (DBN) and diazabicyclo-undecene (DBU), as well as inorganic bases, such as, for example, sodium hydride, potassium hydride, sodium carbonate, potassium carbonate, calcium carbonate, potassium hydroxide, sodium hydroxide and calcium hydroxide.

The processes (b) and (c) according to the invention are also optionally carried out in the presence of a reaction auxiliary. Basic organic nitrogen compounds, such as, for example, trimethylamine, triethylamine, N,N-dimethylaniline, N,N-dimethylbenzylamine, pyridine, 4-dimethylaminopyridine, diazabicyclooctane (DABCO), diazabicyclononene (DBN) and diazabicycloundecene (DBU), are suitable and preferred for these processes.

The chlorinating process (d) can likewise be carried out in the presence of a reaction auxiliary. Certain mineral and organic acids, such as, for example, hydrochloric acid, dilute sulphuric acid, phosphoric acid, acetic acid or propionic acid, and, in addition, acidic salts, such as, for example, NaH₂ PO₄, are particularly suitable for this process.

In processes (a) to (f), the reaction temperatures may in each case be varied over a relatively wide range. Thus

in process (a), temperatures of between 0° C. and 150° C., preferably of between 10° C. and 80° C., are generally employed;

in process (b), temperatures of between 0° C. and 150° C., preferably of between 20° C. and 100° C., are generally employed;

in process (c), temperatures of between 0° C. and 150° C., preferably of between 20° C. and 100° C., are likewise generally employed;

in process (d), temperatures of between -20° C. and +40° C., preferably of between -20° C. and +30° C., are generally employed;

in process (e), temperatures of between 0° C. and 150° C., preferably of between 10° C. and 80° C., are generally employed, and

in process (f), temperatures of between 0° C. and 150° C., preferably of between 10° C. and 80° C., are also generally employed.

The processes (a) to (f) are generally carried out under atmospheric pressure. However, it is in each case also possible to use elevated or reduced pressure.

In order to carry out processes (a) to (f) according to the invention, the starting compounds which are in each case required are employed in approximately equimolar quantities. However, it is also possible to use one of the two components which are in each case employed in a relatively large excess. In general, the reactions are carried out in a suitable diluent and, where appropriate, with the addition of a reaction auxiliary, and the reaction mixture is stirred for several hours at the temperature which is in each case required. In each of the processes according to the invention, working up is effected in accordance with customary methods.

Where appropriate, salts may be prepared from the compounds of the general formula (I) according to the invention. Such salts are obtained in a simple manner in accordance with customary salt-formation methods, for example by dissolving or dispersing a compound of the formula (I) in a suitable diluent, such as, for example, methylene chloride, acetone, tert-butyl methyl ether or toluene, and adding a suitable base. The salts may then be isolated--where appropriate after a relatively long period of stirring--by concentrating or by filtering off with suction (cf. the preparation examples).

The active compounds according to the invention can be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Unica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver Centaurea, Trifolium, Ranunculus and Taraxacum.

Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.

Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Seeale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, on ornamental lawns and sports tuff and on pasture land and for the selective combating of weeds in annual cultures.

The compounds of the formula (I) according to the invention can suitably be used for selectively controlling monocotyledonous and dicotyledonous weeds in different cultures, in some cases, e.g. in wheat, both in the preemergence process and in the postemergence process.

The active compounds can be convened into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquified gases under pressure, and/or solid carriers, optionally with use of surface-active agents, that is, emulsifying agents and/or dispersing agents, and/or foam-forming agents.

In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclo-hexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethyl-formamide or dimethyl sulphoxide, as well as water.

As solid carriers there are suitable: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates; as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foamforming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as albumen hydro-lysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

For controlling weeds, the active compounds according to the invention, as such or in their formulations, can also be used as mixtures with known herbicides, finished formulations or tank mixes being possible.

Suitable herbicides for the mixtures are known herbicides, for example anilides such as, for example, diflufenican and propanil; arylcarboxylic acids such as, for example, dichloropicolinic acid, dicamba and picloram; aryloxyalkanoic acids such as, for example, 2,4-D, 2,4-DB, 2,4-DP, fluroxypyr, MCPA, MCPP and triclopyr; aryloxyphenoxy-alkanoic esters such as, for example, diclofop-methyl, fenoxaprop-ethyl, fluazifop-butyl, haloxyfop-methyl and quizalofop-ethyl; azinones such as, for example, chloridazon and norflurazon; carbamates such as, for example, chloropropham, desmedipham, phenmedipham and propham; chloroacetanilides such as, for example, alachlor, acetochlor, butachlor, metazachlor, metolachlor, pretilachlor and propachlor; dinitroanilines such as, for example, oryzalin, pendimethalin and trifluralin; diphenyl ethers such as, for example, acifluorfen, bifenox, fluoroglycofen, fomesafen, halosafen, lactofen and oxyfluorfen; ureas such as, for example, chlortoluron, diuron, fluometuron, isoproturon, linuron and methabenzthiazuron; hydroxylamines such as, for example, alloxydim, clethodim, cycloxydim, sethoxydim and tralkoxydim; imidazolinones such as, for example, imazethapyr, imazamethabenz, imazapyr and imazaquin; nitriles such as, for example, bromoxynil, dichlobenil and ioxynil; oxyacetamides such as, for example, mefenacet; sulphonylureas such as, for example, amidosulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, cinosulfuron, metsulfuron-methyl, nicosulfuron, primisulfuron, pyrazosulfuron-ethyl, thifensulfuron-methyl, triasulfuron and tribenuron-methyl; thiocarbamates such as, for example, butylate, cycloate, diallate, EPTC, esprocarb, molinate, prosulfocarb, thiobencarb and triallate; triazines such as, for example, atrazine, cyanazine, simazine, simetryn, terbutryn and terbutylazine; triazinones such as, for example, hexazinone, metamitron and metribuzin; others such as, for example, aminotriazole, benfuresate, bentazone, cinmethylin, clomazone, clopyralid, difenzoquat, dithiopyr, ethofumesate, fluorochloridone, glufosinate, glyphosate, isoxaben, pyridate, quinchlorac, quinmerac, sulphosate and tridiphane.

A mixture with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repel-lents, plant nutrients and agents which improve soil structure, is also possible.

The active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in customary manner, for example by watering, spraying, atomizing or scattering.

The active compounds according to the invention can be applied either before or after emergence of the plants. They can also be incorporated into the soil before sowing.

The amount of active compound used can vary within a relatively large range. It depends essentially on the nature of the desired effect. In general, the amounts used are between 10 g and 10 kg of active compound per hectare of soil surface, preferably between 50 g and 5 kg per hectare.

The preparation and use of the active compounds according to the invention can be seen from the following examples.

Preparation examples:

Example I-1 ##STR20##

(Process (a))

0.79 g (0.033 mol) of sodium hydride are added under argon to a mixture of 4.0 g (0.017 mol) of 2-(5,6-dihydro-[1,4,2]-dioxazin-3-yl)benzenesulphonamide and 4.6 g (0.017 mol) of 2-phenoxycarbonylamino-4,6-dimethoxypyrimidine in 20 ml of absolute acetonitrile, and the mixture is stirred at room temperature for 18 hours.
